Clinicopathological Profile of Myelomatous Pleural Effusion: Single-center Real-world Experience and Review of Literature

Background

Multiple myeloma (MM) is a hematologic malignancy of plasma cell origin. MM primarily affects bone marrow, but extramedullary sites can also be involved. Myelomatous pleural effusion (MPE) is an atypical and rare complication of MM. We aimed to systematically study the incidence and clinicopathologic profile of patients with MPE in a real-world setting.

Complete recovery of filler-induced visual loss following subcutaneous hyaluronidase injection

The rise in popularity of hyaluronic acid (HA) dermal filler injection has caused an exceptional increase in the number of cases of reported irreversible blindness. Here, we reported a case of ischemic optic neuropathy and ophthalmoplegia following subcutaneous HA filler injection with complete visual recovery. A 31-year-old Chinese woman presented with sudden onset of right monocular visual impairment associated with diplopia. Patient had received a hyaluronic acid-containing ?ller injection for nasal dorsum augmentation twelve hours prior to presentation. Visual acuity of the right eye was counting finger. A right relative afferent pupillary defect was demonstrated with ophthalmoplegia. Humphrey visual field test disclosed a right inferior altitudinal field defect with impairment of colour vision. Computed tomography of the orbit revealed mild enlargement of the right medial and inferior recti muscles. Our patient showed a tremendous improvement of vision after a subcutaneous hyaluronidase injection with complete visual recovery within 2 weeks.     

Idiopathic neonatal pleural effusion

We present two cases of neonatal pleural effusion, a relatively rare condition, most commonly due to chylothorax. One had bilateral hypoplastic lungs and the other suffered birth asphyxia. Both died before any treatment could be initiated.     

Giant splenic artery mycotic aneurysm presenting with massive hematemesis.

We report a 40-year-old man with rheumatic heart disease who presented with abdominal pain for three weeks and hematemesis for 24 hours. CT scan showed a large splenic artery aneurysm without evidence of pancreatitis. Mycotic aneurysm due to infective endocarditis was considered and confirmed by echocardiogram, which showed aortic and mitral valve regurgitation and vegetations. He was managed successfully with coil embolization of the aneurysm and antibiotics.     

Role of levamisole immunotherapy as an adjuvant to radiotherapy in oral cancer. II. Lymphocyte subpopulations

The effect of radiotherapy and adjuvant levamisole immunotherapy on the lymphocyte subpopulations was investigated. Comparisons were made between the groups receiving levamisole, those receiving placebo and normal healthy controls. Results of a thirty-month follow-up are reported. Radiotherapy caused leukopenia and lymphopenia affecting all the subsets (T, B, TG, and TM), T lymphocytes were affected to a greater extent. This study demonstrates that levamisole does hasten the restoration of T lymphocytes, with the TM lymphocytes showing a faster repopulation in comparison to the TG lymphocytes.     

Presence of a receptor for the active component of Iscador in ascites fluid of tumour bearing mice

Tumour bearing mice exhibit a specific "receptor" in the ascites fluid which binds with the active component isolated from Iscador. This "receptor" was found to be a protein which inhibited the cytotoxicity of Iscador and its isolated active component at low concentration. The receptor protein was also found in the sonicates of tumour cells which are susceptible to the action of Iscador but not in lymphocytes which were not susceptible to Iscador or its isolated active component. The receptor was separated on a Sephadex G-50 column. Activity was lost upon heat denaturation and dialysis.     

p-Amino salicylic acid — oxidized cellulose system: a model for long term drug delivery

The immobilization of p-amino salicylic acid (PASA) on periodic oxidized cellulose (O.C) as a biocompatible carrier was investigated. The immobilization of the PASA is based on Schiff's base formation between the amino group of PASA and the aldehyde group of O.C. The in vivo and in vitro release of p-amino salicylic acid was studied. Such a system may be useful for the sustained delivery of the drugs in the body, since O.C. itself is a biosoluble carrier.     

EGPred: prediction of eukaryotic genes using ab initio methods after combining with sequence similarity approaches

EGPred is a Web-based server that combines ab initio methods and similarity searches to predict genes, particularly exon regions, with high accuracy. The EGPred program proceeds in the following steps: (1) an initial BLASTX search of genomic sequence against the RefSeq database is used to identify protein hits with an E-value <1; (2) a second BLASTX search of genomic sequence against the hits from the previous run with relaxed parameters (E-values <10) helps to retrieve all probable coding exon regions; (3) a BLASTN search of genomic sequence against the intron database is then used to detect probable intron regions; (4) the probable intron and exon regions are compared to filter/remove wrong exons; (5) the NNSPLICE program is then used to reassign splicing signal site positions in the remaining probable coding exons; and (6) finally ab initio predictions are combined with exons derived from the fifth step based on the relative strength of start/stop and splice signal sites as obtained from ab initio and similarity search. The combination method increases the exon level performance of five different ab initio programs by 4%-10% when evaluated on the HMR195 data set. Similar improvement is observed when ab initio programs are evaluated on the Burset/Guigo data set. Finally, EGPred is demonstrated on an approximately 95-Mbp fragment of human chromosome 13. The list of predicted genes from this analysis are available in the supplementary material. The EGPred program is computationally intensive due to multiple BLAST runs during each analysis. The EGPred server is available at http://www.imtech.res.in/raghava/egpred/.
